Two different computer systems are monitored for a total of n weeks. let xi denote the number of breakdowns of the first system during the ith week, and suppose the xi’s are independent and drawn from a poisson distribution with parameter l1. similarly, let yi denote the number of breakdowns of the second system during the ith week, and assume independence with each yi poisson with parameter l2. derive the mle of l1, l2, and l1 – l2. [hint: using independence, write the joint pmf (likelihood) of the xi’s and yi ’s together.]

step-by-step explanation:

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
